SHIMANO 105 Di2 Rear Derailleur 2X12-speed

A new level of performance for SHIMANO 12-speed road rear derailleurs

Wide 36T-compatible 12-speed Di2 rear derailleur. Receiving the wireless shifting signal from the shift lever, the SHIMANO 105 rear derailleur completes a shift in the blink of an eye with its high-performance motor and optimized link structure.
